As science continues to bridge technological innovation with Earth's natural processes, the future of earthquake research grows brighter.
Now, in a recent press release, a team led by Professor of Geophysics Zhongwen Zhan has introduced an innovative method called distributed acoustic sensing.
In Southern California, around 500 seismometers span the vast expanse of approximately 56,500 square miles, each with a price tag of up to 50,000 dollars. In contrast, leveraging fiber optic cables could virtually blanket the region with millions of cost-effective seismometers.emitters at one end of the cable, sending light beams through the glass strands comprising the cable's core.
In the study, the team focused on light signatures within a segment of fiber optic cable located in the Eastern Sierra Nevada during the 2021 Antelope Valley magnitude 6 earthquake.
